EDWARD POSSON, OF CHICAGO, ILLNOS.

CAR-DOOR.

Specification of Letters Patent.

Y 0 all whom it may concern.

Be it known that I, Emmen Possono citizen of the United States, residing,r at Chicago, in the county of Cook and State of illinois, have invented certain new and useful Improvements in Car-Doors. of which the following is a specification.

The principal object of my invention is to rovide a new and improved outside door for railway freight ears.

Another object of my invention is to provide an improved grain-tight outside door for freightcars.

Still another object of invention is to provide improved means for operating such a. door.

A further object of my invention is to provide means for fastening the door -in closed position.

All these objects and others will be made apparent in the following` speeilieation and claims, taken in connection with the act-einpanying drawings.

For the purpose of elearljiIv explaining;` the nature of my invention l hare illustrated one Specific embodiment thereof in the ateon'ipairyingr drawings.

rlhe invention is detined in the appended claims.

Referring; to the drawings- Figure V1 is a side elevation of my'improved door; Fig'. 2 is a vertical section laken on the line 2--2 of Fig. l; Fig. 3 is an enlarged section of the lower part ofthe door, taken on the line 2--2 of Fig 1 Figs. 1v., 5 and ti are horizontal l tions taken on the correspondingly numbered lines in tig. 2i Fig. 'i' is an elevation of certain parts at the lower right hand corner of the door as viewed in Fig. 1 g Fin. 8 is an elevation of a. latehing tongue; liigr. 9 is an elevation of a handle and assoeiated elements of apparatus; Fig. 1t) is a horizontal section taken on the line 10"710 of Fig. 7; Fig. 1l is a. horiiontal section t: ken Fig. l) is a vertical section taken on the line 12---152 el" Fig. 7; Fig. 13 is a vertical axial section taken on the line IBM-13 of 19u57; Fig. 14 is ay vertical. section taken on the line 1%14 of Fig. 13; and Figs. 15, 1 6 and 1T are perspective views of certain interlocking parts shown in elevation in Fig'. Si.

The side wall 21) oit' the freight ear has the I-lllsual door opening adapted to be closed by #the door7 which 1s designated generally by .Y

`when the door closed.

the reference numeral 21. rl`he door openmg is bounded at the sides by the posts 22 and 23, and at the bottom by the sheet metal plate 25 resting on the. floor 21. Between the floor and the supporting' side sill 26 lies the web 2T of a T-bar 2T-@28, whose head is 28. This T-bar eitends below the door opening' .and for a considerable distance to the right thereof. and constitutes a supporting and guiding traek for the door. At. the right', as viewed in l, the web of the T-bar is cut away so asito leave tongues 29h which are bent down and bolted to the side wall. rThis part of the T-bar 2l-28 has a series of perfor-ations 10) adapted to be. engaged by the teeth of the gear wheel 75.

The door post- 22, against which the. leading` edge of the door closes, is reinforced by a sheet. metal member 30. and the other door post 23 is reinforced by a sheet metal member 31. These members 3() and 3l have. their inner edges turned in and seated in vertical ebannes that are rabbetedein the inside faces of the door posts. The member 30 has its outer portion folded bark against. the door post, as designated 33, and then again folded, as designated 31, so as to form a socket 3S to reeeire the leadingV edge '11G of the door when it is closingJ The space 38 is mainla ined by means of interposed washers 55, through which the bolts 3G pass. The entre/nie edge of the member 3() is doubled. as at 3T, to give it a proper finish and still-y ness. The outer edge of the sheet metal member 31 is folded bark at right angles and spaced from the. door post 23, as indicated at 39, and the following edge of the door has secured thereto a channel piece '11 by means of the rivets Il2. This ehannel strip engages the edge Slt) of the member ill (,)ver the top of the door opening is a which has a ehaunel eut on its outer face. This channel is oi'erhung by a sheet metal lip 44. thus proridiineT a slot or guide between the members 4?; and 4.1- for the upper edge of the door 9.1.

At the lower left hand edge of the door. as .viewed in Fin'. 1, there is a east-iron bracket 45, with an extension piece '16 that hooks under the head of the T-rail BTM-Q8. This bracket carries a roller 41-7 to run upon the head 2S of the l"iail. At the other lower corner of the door there is another cast-iron bracket 48 with an extension part Patented Sept. l5, 719141 ooden member 13.

103 that hooks under the head 28 of the l handle S3. Within the cylindrical member T-rail guiding and supporting track. This bracket has a roller Li9 engaging the rail 2S. The head of the T-rail track is slightly recessed under the rollers a7 and 4:9 when the door is closed, as indicated at 10ft. These rollers are carried on members that go into sockets in the respective brackets Ll5 and 48. Shims can be introduced through the slots 105 to adjust the height of the rollers 17 and 49 relatively to the door. Y

The sheet metal door 21 is strengthened in its lower part by transverse ribs 50. ln its upper part there is an opening adapted to be closed by the sub-door 51, which is strengthened by the transverse ribs 52. This sub-door moves in the lateral vertical guides 53. J ust below the sub-door the main door is strengthened by the transverse ribs 5i, which, however, do not project out far enough to interfere with the vertical move- 21 carries an overhanging lip 55, which is engaged by the upper edge of the sub-door when the latter is closed. The lower edge of the sub-door carries a hooked lip 56 that engages the stationary down-turned flange 57 when the sub-door is closed. The arm 5S has its forked ends 59 pivot-ally connected with the sub-door 51, and at its lower end is the operating handle 60, whereby the sub-door may be raised and lowered.

A small opening in the lower part of the main door is adapted to be closed by a subdoor 01, which Amoves horizontally in the upper and lower guides 62 and 63. This sub-door 01 has a hooked lip 611 which closes its following edge, and its leading edge enters a stationary lip G5. sub-door 61 is a bracket G6, with a jaw 07 adapted to be engaged by a tongue 106 which depends from the bar 5S. This bar also carries an inward projection 0S adapted to go into the socket att-ached to the door 21. This projection and socket have registering perforations G9 and 71, adapted to be engaged by the bolt 72 which slides in the socket 74.. The remote end of the bolt 72 is bent down, as designated 73. lVhen the door is locked, this down-turned end 73 lies in the notch 10Q of the bracket 4S.

A gear wheel 75 has its teeth adapted to engage the perforations 109 in the T-rail. Thus the latter constitutes kind of rack to coperatie with said gear wheel, which wheel is cast integral with a cylindrical port-ion 76 bounded by a {ianfre 77, as shown in Fig. 13. The bracket is formed with a curved socket 7 8, bounded above and below by the projecting jaws 79. The cylindrical inember 7 6 lits in this socket and is retained by the block 80, which goes between the jaws 79 and is secured lbythe bolt Si. The gear wheel 75 also carries integrally therewith a transverse sleeve 82, within which slides the Attached to the l 76 is a space 84, with guides 88 for the plunger S5. carrying the head 86, under which is the spring 87 that causes the head to push against the bar 83. The inside of the sleeve 82 is beveled at 107, as indicated in Fig. 11.4

The ends of the bar 83 have rivets 89, so that the bar cannot escape from the sleeve.

The lower part 103 of the bracket d8 has a head 90, with its spindle 91 rotatably mounted therein. Pivoted to this rotatable head is a hasp 92 with a project-ion 93 adapted to enter a hole 911 in the handle 83. The hasp also has a tongue 95, perforated at 96, and this perforation is adapted, when the h'asp is closed, to register' between two holes 97 on respective lugs that vproject out from the bracket 4S. A latching member 98 pivoted on the bracket 4S carries a tongue 10S adapted to engage the registering holes 9G and 97.

The latch 98 'is pivoted at 100, and a leaf ment of the sub-door. At its top the door l spring 99 tends to hold it in normal operative position. Registeringperforations 101 in the latch 98 and an adjacent lug that projects from the hasp facilitate fastening the latch by means of an ordinary car door seal.

Supposing that the car is loaded with grain, and it is desired to unload the same and open the door, the seal through the perfor-ations 101 is broken, the latch raised, and 'the hasp thrown down. This permits the arm 7 3 on the bolt 72 to be thrown out,

and then said bolt is pushed to the right, as

viewed in Fig. 1. This unlocks the projection GS from the socket 70 and permits the handle 00 to be pulled out, thus removing the tongue 106 from the socket 67 and perf lnitting the sub-door 01 to be moved to the left. Thereupon the grain adjacent to the door flows out through the small lower 'opening` in the door 21. After the pressure has been relieved, the operator takes the handle SS and rotates the gear 75, thus opening the main door 21. lf the operator linds it inconvenient to carry the handle 83 clear around` he can give it half a revolution and then slide it lengthwise through the socket- 28 alternately. After the main door is opened, the remaining grain in the car can be removed by usual well-known methods.

When it is desired to close the door, this is done by rotating the handle 83 in the appropriate direction. The upper sub-door 51 can be left open temporarily for introduc ing grain through a spout. The operation of completely locking the arts in closed relation will be readily understood from the foregoing description of how they are unlocked.

lt will be seen that a single seal secures the latch that locks the main door, the opel ating handles, and both sub-doors.. Y The lower edge of the door 21 lies inside of the nlhead 28,A and thus makes a grain-tight .lock the handle in position.

vadapted to engage said socket and another closure across the bottom. The door also makes a grain-tight closure at its sides, as shown in Figs. 4f and 5.
